Shock absorbers KONI or Sachs

I went with Sachs dampers which are OEM but sportier than my stock zhp dampers. I don’t regret it one bit

I also felt that swapping to Koni shocks in the rear made the car feel better to drive -- the stock rear shocks didn't have much low speed rebound, so the trunk would feel like it was floating if I went over crests. The Konis fixed that.

I got Koni Yellows. Adjustable dampening and they don't rattle/clunk like the Billstein B6's apparently do.

Konis are amazing, I won't ever run anything else.

I have a set of the adjustable yellow sports using the stock springs. Firm but not harsh, I run them around halfway between soft and hard. One of the best upgrades I've done.

I’m quite partial to koni struts/shocks. You can adjust the rebound rate to make them softer for your commute but stiffen them up when you get to hit those mountain roads

Plus they work on stock springs if you’re like me and like the car not bottoming out

After almost two months and driving 4000 kilometers on varying quality mountain roads, I think I made a good decision when opting for the Koni Special Actives for my 2006 Mazda3. I expected them to be a bit softer, as they are stiffer than the Koni FSD. They are not uncomfortably stiff, shielding people inside the car from harsh roads and speed bumps. The car feels really stable. Summarizing my impressions so far: reduced high frequency noises and jolts, reduced body roll and pitch, increased stability, the car feels more composed even in extreme situations, and feels more premium. The faster I go on bad roads, the smoother it feels.

Sachs are great! Came stock on the SR 2016 Altima and they ride great, stiff and sporty.

I have the Koni yellows. Stick with OEM Sachs. Unless you are doing a ton of freeway miles, or want the feel of a go-cart(which is a little fun), the shocks are not worth the ride or the money. The ride is too stiff for street, but absolutely perfect on the highway cruising over 85mph for hours.

My experience with Koni Orange STR.T shocks has been less than favorable. I have them on my 2006 Jetta TDI and they are absolute crap. Far worse than the blown out OEM shocks they replaced.
